TOBACCO-PIPE.

,V'o all whom it may concern.'

vBe it known that we, GUs'rAv KNocI-IEN- IAUER, market-gardener, and CARL BEUTHE, naster turner, subjects of the German Emieror, residing at Schaala, near Rudoltadt, and Rudolstadt, Thuringia, Gernany, have invented certain new and useful mprovement-s in and Relating to Tobacco- .ipes, of which the following is a specifiation.

Our present invention relates to improvenents in and relating to tobacco pipes and las for its object to provide an improved levice for intercepting saliva and dust and vhich device at the same time forms aconlection between the pipe bowl and the mouthpiece. As such a connecting tube it .voids the necessity for the usual screw hreads or screwed connection between the mouthpiece and pipe, and permits, when [sed in meerschaum pipes for example, a vide bore to be given to the upper part, at he same time avoiding the use of the usual crewed nipple made of bone, which coniects the mouthpiece with the pipe. It is vell known that this screwed nipple or conlecting `piece in the case of meerschaum ipes can only be made with a very small ore as the meerschaum which holds this crewed connecting piece has very little trength. The small bore of the screwed iiece, however, obstructs the draft in such aeerschaum tobacco pipes. As however the resent connecting or intermediate piece `llows the meerschaum tube, as well as the mouth-piece to be made with large bores, n easy and agreeable smoke is obtained and he duration of the life of the parts of the ipe is considerably increased.

The connecting piece according to the resent invention is so arranged that a disk raving a central hole is put into the tube mrtion, which disk at the end is provided rith a peripheral flange turned toward the iouthpiece of the pipe and has in the enter` a tubular extension which, however, loes not reach up to the end of the mouthliece. At the back of the disk toward the `owl a dust filter is provided in the shape f a wedding plug which is kept in posiion by means of a wire tissue and can be asily removed. The connecting piece is ushed over the mouthpiece and a short tem on the bowl, andin this way holds oth these parts well together; without it Bpeciiication of Letters latent.

being necessary to use any of the usuall connecting means such as screw threads. By using the connecting piece the manufacture of such kinds of pipes is considerably cheapened. Owing to the fact that the moisture in the pipe is for the most part due to saliva which runs along the bore of the pipe stem through the mouth piece, and that this collection of saliva isv retained in the connecting piece by the tubular extension which projects toward the mouthpiece, and therefore cannot reach to the pipe bowl, a clean smoke and good and regular combustion of the tobacco which does not get moist is obtained. By removing the mouthpiece the collected moisture may easily be removed from the connecting piece. The filter retains the tobacco dust Whichis drawn from the bowl by the suction in smoking.

Figure l is a side View of the pipe, partly in section, illustrating one form of our invention. Fig. 2 is a cross sectional view on line A-B of Fig. l. Fig. 3, is a cross sectional view on line C-D of Fig. 1.

The disk b has at its backthe filter comprising a cartridge c which is held in position by means of a suitably large-meshed tissue e. The end a1 of the connecting piece is connected to the mouthpiece at the end e1. The stem of the pipe f is inserted in the other end a2 of the connecting piece.

vThe sockets al and a2 may be slightly tapered so as to make a sufficient-ly tight joint with the mouthpiece c, and the tube f of the pipe piece g.

When the pipe is in use the saliva which flows from the mouthpiece collects in the annular chamber between tube d yand the top partof the connecting piece a, and can easily be poured out of this chamber after pulling out or twisting oii the mouthpiece.w When drawing at the mouthpiece, the tbacco smoke passes through the filter or dust collector e, and enters the mouthpiece freed from dust through the tube ci.

A similar connecting piece may also be used for cigar holders and long pipes. As already mentioned it permits of an easy connection between the pipe bowl tube and the mouthpiece, which is permanently insured and renders the provision of special screwed pieces between the bowl tube piece and the mouthpiece unnecessary. Nor does it cause the pipe to dra'w hard. This connetting piece is also very suitable OI clay pipes. For this purpose the stem of the pipe Vnext to the stem and having a centrally disposed opening therein, said disk having inner and outer tubular members projecting toward the stem.V

2. The combination with a pipe bowl with a stem, of a relatively elongated sleeve connecting the stem and bowl with t-he ends Copies of this patent may be obtained for of the bowl and stem relatively widely se arated, a cartridge of fabric dividing t e sleeve into two compartments and located at a relatively considerable distance from the facing ends of the bowl and stem, and a disk-like member engaging the cart-ridge on that side thereof next to the stern and having a central opening disposed therein, said member having an inner tubular projection extending from said opening toward but not into contact with the stem, and an outer tubular member surrounding said inner projection and engaging and disposed wholly within said sleeve.

In testimony whereof we haveA hereunto set our hands in presence of two subscribing witnesses.
